Have a water leak (solved) over fuse box behind.

Have a water leak (solved) over fuse box behind passenger kick panel. Car had started doing odd things (all gauges going troppo when ignition turned on, radio stopped working, no elec mirrors) after jump starting, but now after finding leak over fuse box and auto electrician replacing near all fuses, the radio works and the mirros. But now air con wont work, no temp gauge. And engine management light on dash.

Help before it ends up costing me a limb, or even my youngest child
